Write the code to MainMessageHandler:

 

Code Snippet

case WM_KEYDOWN:

  if (wParam == VK_DEL) {  // Or another of your key

  // execution of code

  }

  break;

 

In lParam are additional params. For information about the parameters in lParam see http://msdn2.microsoft.com/en-us/library/ms646280.aspx.
